Abstract: 120,227. Balanced Engine Syndicate, Kerr, R. P., and Riley, W. A. Aug. 27, 1917. Two-stroke-cycle engines; driving-gear; pumps, barrels for.-Engine units as described in Specifications 6102/09 and 6751/09 have their cylinders disposed in a plane at right-angles to a pair of geared crank shafts c, d. The engine is reversible. Fig. 1 shows one of a number of parallel units, arranged transversely to the crank shafts, in which the lower pistons carry cylindrical crossheads 3 and the upper pistons rectangular crossheads p, p<1> which reciprocate in pump cylinders delivering scavenging air to a chamber t communicating with the cylinder admission ports. A modification is described in which the cylinders are disposed in three radial planes, and in a further modification the cylinders of a unit are inclined to one another, the cylinders being farther apart at their crank shaft ends than at their pump ends. In an engine arranged as shown in Fig. 1, the crank shafts are connected together directly by double helical gearing e, f. With engine units disposed on both sides of a transmission shaft 5, as shown in Fig. 4, the crank shafts c are connected to the shaft 5 through intermediate helical wheels 8 and shafts d directly through wheels f, 6. A coupling 9 enables one of the engines to be put out of commission. To prevent fouling of the driving-rods &c. in the event of failure of the helical transmission gearing, large wheel teeth may be formed on the crank disks which keep the crank shafts in their correct angular positions until the engine can be brought to rest. The power shaft may be at right-angles to the crank shaft.

Title: Improvements in and relating to means for the automatic regeneration of the vacuum in vacuum containers
IPC: H01J41/14
Filed: 1930-04-24
Abstract: 351,641. Maintaining high vacua. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats Ges.; 2, Friedrich Karl-Ufer, Berlin.) April 24, 1930, No. 12694. Convention date, April 24, 1929. [Class 8 (i).] The vacuum in a container more particularly a high vacuum switch container is maintained by making use of a relay, controlled by the positive ion current which flows when the pressure reaches a predetermined limit, which connects a heating device for the vaporization of a regenerating substance such as calcium, barium, or magnesium. The container 15 has an extension in which a glass tube 1 containing the regenerating substance is situated, and an extension 5 enclosing a grid 13, a filament 12, and an electrode 14. When the vacuum in the container is reduced, a sufficient current flows between the grid 13, and the electrode 14, to operate a relay 4, closing the circuit of a heating filament 2 and resulting in the vaporization of the regenerating substance which reduces the pressure in the main container. An electrode 7 may be introduced close to the filament 2 and positively charged with respect to it, so that the emission of electrons from the filament 2 is accelerated to bring about ionization of the gases and vapours. The electrode 7 may be continuously charged or only when the relay 4 operates. To prevent the vaporization of the regenerative substance in the tube 1 during the initial evacuation of the container 15, the tube is at first sealed and heated by means of the filament 2 to open at a weak spot 3 after the container 15 has been treated.

Filed: 1947-05-10
Abstract: 633,729. Pick-up mountings. DART, F. H., and M.S.S. RECORDING CO., Ltd. May 10, 1947, No. 12711. [Class 40 (ii)] A disc record sound reproducer is carried at the end of an arm extending from a carriage guided to move in a straight line, and when the arm is tilted to disengage the reproducer from the record, a biassed ball or like element makes yielding engagement with a threaded rod which can be rotated manually to position the carriage and reproducer. As shown in Figs. 2 and 4, a sound reproducer 9 is carried at the end of an arm 10 rigidly connected to a block 7 which runs on wheels 8 along a V-groove 6 in a straight bar 5 mounted between end posts 2, 3 fixed relative to the motor board. During reproduction the reproducer thus moves approximately along a radius of a disc record on a turntable 4. The edges of wheels 8 are radiused to permit any necessary tilting of block 7 about an axis parallel to bar 5 during reproduction. A lever 13 may be moved from the position shown to rotate an eccentric rod 12 into engagement with a projection 11, which may be a counterweight, on block 7 and thereby raise the reproducer from the record. In this position a spring-loaded ball 18, retained at the end of a pin 17 mounted in a sleeve 16 on the upper side of block 7, engages a screwed shaft 21 mounted between end posts 2, 3 so that the reproducer may be set to a desired position on the record by rotation of control knob 15 of shaft 14. This setting is facilitated by calibration of a scale 22, over which moves a pointer 23 carried by block 7, and calibration of knob 15 both of which are related to the pitch of the record groove. Reproduction of cued records in succession is referred to. Spring-loaded ball 18 permits movement by hand across the record of the reproducer in its raised position, the required degree of engagement between ball 18 and shaft 14 being set by a screw 21 locking pin 17 to sleeve 16.
